Perfectly Grilled Orange Roughy

Here’s my go-to grilled orange roughy recipe, with a straightforward cooking method that brings out the fish’s natural flavor, seasoned simply with lemon, herbs, and a touch of garlic butter.

This orange roughy dish has become my weeknight dinner hero. I make it at least twice a month because it’s quick and my whole family actually eats it without complaints. Plus, the leftovers make great fish tacos the next day – if there are any leftovers!

What Kind of Orange Roughy Should I Use?

Fresh orange roughy is your best bet for this recipe, though you’ll most likely find it frozen at your local grocery store since it’s typically caught in deep waters far from shore. If you’re using frozen fillets, make sure to thaw them completely in the refrigerator overnight and pat them dry with paper towels before cooking. Look for fillets that are firm and white with no discoloration – they should be about 1-inch thick for ideal grilling. Since orange roughy is a mild-flavored fish, the quality really matters, so try to buy from a reliable seafood counter or store where you can ask about the sourcing and when it was caught or frozen.

Options for Substitutions

This simple grilled fish recipe can be adapted with several easy swaps:

• Orange roughy: Since orange roughy can be hard to find, you can use other mild white fish like cod, halibut, tilapia, or sea bass. Just adjust cooking time based on the thickness of your fish – thinner fillets will cook faster.
• Olive oil: Any neutral cooking oil works here – try avocado oil, grapeseed oil, or even melted butter for a richer taste.
• Lemon: Out of lemons? Orange zest and juice can work too, or try lime for a different citrus kick. If using lime, use a bit less as it’s typically more tart.
• Fresh dill: Fresh herbs are best, but if you don’t have dill, try fresh parsley, basil, or thyme. In a pinch, use dried dill (about 1 teaspoon), but add it to the oil mixture rather than as a garnish.

Watch Out for These Mistakes While Grilling

The biggest challenge when grilling orange roughy is preventing this delicate fish from sticking to the grates – make sure to oil both the fish and the grill grates thoroughly, and only flip the fillet once during cooking to avoid breaking. The second common mistake is overcooking, which can happen quickly with this lean fish – cook for just 3-4 minutes per side until the flesh turns opaque and flakes easily with a fork. To keep the fish moist and flavorful, avoid pressing down on it with your spatula while grilling, as this squeezes out the natural juices and can lead to a dry final result. For the best outcome, let your fish come to room temperature for 15 minutes before grilling, and make sure your grill is preheated to medium-high heat (around 375-400°F) before adding the fish.

What to Serve With Orange Roughy?

This light and flaky fish pairs perfectly with simple sides that won’t overpower its mild, sweet flavor. A bed of fluffy rice pilaf or couscous makes an excellent base, soaking up the lemony juices from the fish. For vegetables, try roasted asparagus or steamed green beans tossed with a little butter and almonds – they’re quick to prepare and ready in about the same time as the fish. You can also add a fresh element to your plate with a simple cucumber and tomato salad dressed with just a touch of olive oil and herbs.

Storage Instructions

Keep Fresh: Got leftover grilled orange roughy? Pop it in an airtight container and keep it in the fridge for up to 2 days. The sooner you eat it, the better it’ll taste – fish is always best when it’s fresh!

Pack: If you’re taking this for lunch the next day, store the fish separately from any sides like salad or vegetables. This helps keep everything tasting fresh and prevents any fishy flavor from spreading to your other foods.

Enjoy Later: When you’re ready to eat your leftover fish, try serving it cold on top of a salad – it’s actually really good this way! If you prefer it warm, gently heat it in the microwave at 50% power in 30-second intervals until just heated through. Be careful not to overheat, as this can make the fish dry and rubbery.

Ingredients

• juice of 1/2 lemon
• 1 tsp grated lemon zest
• 1 orange roughy filet (8 oz)
• black pepper (freshly ground, to taste)
• 1 large sprig fresh dill
• 1/4 tsp salt (kosher, for a cleaner taste)
• 2 tsp olive oil (extra virgin, for richer flavor)

Step 1: Prepare the Fish

Place the fish in a glass dish.

Drizzle both sides of the orange roughy with olive oil, ensuring it’s evenly coated.

Season both sides with salt and pepper to your taste.

Next, sprinkle lemon zest over the top of the filet and pour fresh lemon juice over it for added flavor.

Step 2: Add Fresh Dill

Pull the fronds from the dill stem and gently sprinkle them over the top of the orange roughy.

This will infuse the fish with a mild, aromatic taste that complements the zesty lemon.

Step 3: Prepare the Grill

Heat a gas grill to medium heat.

Take a moment to brush the grill grate with olive oil, which will help prevent the fish from sticking and create those beautiful grill marks.

Step 4: Grill the Fish

Carefully place the fish filet on the grill, with the herb and zest side facing down.

If you are also grilling lemon slices for garnish, place them directly on the grill grate as well.

Cook the fish and lemon slices for about 5 minutes on each side.

The fish is done when it flakes easily with a fork or reaches an internal temperature of 145°F (63°C).

Step 5: Serve and Enjoy

Once cooked, remove the grilled orange roughy from the grill and place it on a serving plate.

Top with the grilled lemon slices, if desired, for an extra burst of citrus flavor.

Serve immediately and enjoy the fresh, zesty taste of your grilled fish.
